The duo is well known for helping to establish the popularity of salsa music in the 1960s and 1970s. They are also notable for fusioning elements of classical music and rock with traditional latin music. Among their biggest hits were "Richie's Jala Jala", "Agúzate", "El Sonido Bestial", and "Bomba Camará". They are also famous for their christmas songs "Seis chorreao", "Bomba en Navidad", and "Bella es la Navidad".

The duo was popular from 1965 to 1974 throughout Latin America and the United States, specially in Caribbean countries. In 1974, following a conversion to Evangelicalism and the inclusion of religious themes in the song's lyrics, the duo's popularity fell. The group continued releasing albums but broke up in the 1990s.[1] In 1999, they reunited,[1] and they have been touring and releasing new albums since then.
